`To all whom t may concern:

Beit known that I, 'HERBERTE SMITH, a citizen of the United States, residing at Spokane, in the countyof Spokane and State of d/Tashington, have invented certain new and useful Improvements in Railway ldail-Deliveries, of which the following is a specification.

The present invention relates to improvements in railway mail delivery, and particularly to features for vertically adjusting "the mail receiving devices so that the mail pouches, when delivered, may be received withaccuracy and reliability thus eliminating danger of losing -the mail pouches during an exchange.

The invention contemplates, also, an improved construction and arrangement in the iail exchange devices involving the vertically adjusted upper arrn of the receiving device in conjunction with a resilient, lower, supporting arm for the delivery device, as will be hereinafter pointedy out and claimed.

The drawing illustrates vthe preferred form of the invention, constructed and arranged according to the best mode so far devised for the practical application of the principles of the invention, and this present application embodies subject matter of the entire apparatus for which other applications for patent are being tiled, covering separated features of the apparatus.

'The invention is illustrated in connection Y with the usual mailcar C' which has the customary type of vertical, revoluble standard 1 (the revolving means being not illustrated in this application). The standard revolves as required in bearings 2, 2, attached at the side of the car in proper proximity to the doorway thereof.

The standard is provided with an upper receiving arm 3 and its complementary arm -1 having the respective receiving forks 5 and G and each arm has a perforated head, as 7 and S movable on the standard, vertically,

Vthrough the instrumentality of a screw bar 9 in order to adjust the arms with relation to each other.

The screw bar is revolubly supported Yin a bearing boss 10 integral withand vprojecting from the standard 1, and the screw bar 9 has a pair of upper and lower collars 11 11 for holding the bar against vertical movement with relation to the boss, and for guiding the bar inrits revolving movement in the boss. l

The threaded ends 12 of the screw bar are passed through the threaded perforations in the two heads 7 and 8 of the respective arms 3 and 4 and by means of a nut portion 13 the screw bar is turned. Turning of the screw bar, which remains stationary with relation to the standard, of course causes the heads and their arms to be moved upward or downward while remaining equidistant from each other, and in this manner the arms are adjusted to receive the mail pouches as they are delivered.

During the exchange of mail, the pouches I 14 that are to be delivered, are supported by the suspending cords 15 attached at the upper. end to the suspension device 16 on the upper receiving arm which also acts as the upper delivery arm, and the lower delivery arm is a speciallyv constructed resilient or spring arm 17 with a suspension or retaining device 18 at its free end, and fixed on the standard by itsv head 19.

In dotted lines the spring arm is illusytrated to show its resiliency, while iny full lines it is held under tensionby the cable or cord 15, and of course the resiliency of the spring arm holds the cable taut so that the suspension devices 16 and 18 are held against accidental displacement. In addition to the resiliency feature ofthe delivery device, it will be apparent that the delivery device may be adjusted through the medium of the screw bar 9 to vary the distance be-` tween the upper receiving arm which is atr the same time the delivery arm, and the lower resilient, delivery arm, these features insuring a reliable device for holding or retaining the pouches until the delivery takes place in usual mannergY From the above description taken in connect-ion with the drawing it is evident that the exchange device, including both the 'receiving and deli-very operations, may be readily adjusted with reference to the revoluble standard to adapt the three arms for diferent vconditions arising in actual use,

for proper operation of the exchange apparatus.

Claimsi Y 1'.. The combination in a railway mail exchange with the revoluble standard of a pair of vertically movable receiving arms and a delivery arm, means on one of the receiving arms to co-act with the delive arm for suspending a pouch to be delivere and positive means for adjusting the recelving arms. 3

2. The combination in a railway mail eX- change with the vrevoluble standard, of a pair of receiving arms and means for adjusting them` with relation to each other,

and a delivery arm below said receiving arms, and means on the upper receiving arm to co-act with the delivery arm for suspending a pouch to be delivered.

3. The combination in a railway mail exchange with the standard, of a pair of adjustable receiving arms, and a resilient delivery arm below these arms, and the upper receiving arm having means to co-act with the resilient delivery arm for suspending a pouch to be delivered.

4. rlhe combination with a standard of a pair of receiving arms each having a perforated head movable on the standard and a bearing on the standard, of a screw bar having its threaded ends in the perforated heads and revolubly supported in the bearing and a resilient delivery arm below these arms, and the upper receiving arm having means to co-act with the resilient delivery arm for suspending a pouch to be delivered.

In testimony whereof I aix my signature.
